Answer: 7:50 AM
Step-by-step explanation:
The clock goes to 60 minutes so if you subtract 10 from 8:00 AM
It will start at 7:60
7:60-10 is 7:50
Your method is right so u already know how to do it
Answer:
80 hours
Step-by-step explanation:
let d represent doug, let l represent laura
first, set up a system of equations representing the problem:
since doug spent 10 less than twice the hours laura did, and we know that the total amount of hours they spent together is 230:
l=2d+10
d+l=230
then solve:
*first i rearranged the equations so i can solve this system of equations using elimination method*
l-2d=10
l+d=230
*subtract*
3d=240
d=80
so, doug spent 80 hours in the lab
Try 18 and then multiply the sum of 2 and 18 to 7
Answer:
She is incorrect
Step-by-step explanation:
The fundamental theorem of algebra states that if a polinomial has a degree n, therefore has n roots. To fidn these roots the use of complex number imay be necesary .
For the equation, degree is 3, so there are 3 solutions.
